Brown corundum (alumina, corundum sand) is suitable for various dry and wet treatment processes, and can polish the rough surface of any workpiece finely. It is one of the most economical abrasives. This sharp synthetic abrasive with water chestnuts has a hardness second only to diamond, making it particularly suitable for use when strict requirements are placed on iron pollution. It is used for the roughest cutting and can also be made into a pebble shape for processing precision sized workpieces to achieve extremely low roughness. Due to its high density, sharpness, and water chestnut structure, it is currently one of the fastest cutting abrasives.
Brown corundum (corundum sand) is produced by electrically melting high-quality alumina ore, while high-quality aluminate is used to produce powder corundum and white corundum. Their natural crystal structure gives them high hardness and fast cutting performance. At the same time, they are often used as raw materials for bonded and coated grinding tools.
Brown corundum (corundum sand) can be recycled multiple times, depending on the material grade and specific process. Most standard abrasive sandblasting equipment can be used.
